The COS-B Satellite

The ESA mission COS-B, along with NASA's SAS-2,
provided the
first detailed views of the Universe in Gamma-rays. COS-B carried a single
large experiment, the Gamma-Ray Telescope, which was responsibility of a
group of European research laboratories know as the
Caravane Collaboration. Launched on the 9 August 1975, COS-B was
originally projected to last two years, but it operated successfully for 6
years and 8 months. It provided the first complete map of the Galaxy in
gamma-rays.
